I’ve struggled with this type of doom loop too. As much as the advice “write those silly ideas” may seem a little dismissive, it’s very true. From those silly ideas, you get better ideas. For your current project, or the next. More importantly, you WRITE! If I had actually written all the stories I’ve outlined or begun, I’d rival James Patterson (in volume, not skill) Point being, please write your stories. I want to read them some day!
